CONTROLLING APPARATUS FOR AIR-PRESSURE SYSTEMS FOR PUMPS.

Application filed July 5,

To all whom "it may concern:

Be it known that I, AUGUsT F. HARE- NIGHT, a citizen-of the United States, residing at Tinley Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Controlling Apparatus for Air-Pressure Systems for Pumps, of which the following is a specification.

This invention is quite similar to that disclosed in my co-pending application Serial No. 620,820,'filed February 23, 1923, for a like apparatus, and embodies improvements over the structure set forth in said application, as well as improvementsin air pumping apparatus generally.

My present application, like the above mentioned co-pending application, while being more particularly intended for use in pumping Water from earth wells and cis terns, yetis applicable for use in pumping water or liquids from various kincs of coir tainers whether located above ground or below the same, and has for its principal object to provide a pneumatically operated pumping apparatus which shall be automatic and efficient in its operation, simple and inexpensive in construction and inst21llation, strong, durable, and with its parts so constructed and arranged as to be easily accessible for changes and repairs.

Another object of my present invention is to improve, simplify, render more eiiicient, and avoid certain diiiiculties heretofore encountered in the means or connec ions for controlling the flow of compressed air from a reservoir therefor to, from, and through certain parts of the apparatus.

Other objects and advantages of the invention will be disclosed in the following description and explanation.

The invention consists in certain peculiarities of the construction, novel arrangement and combination of the various parts thereof a s will be hereinafter more fully described and explained, which explanation will be more readily understood when read in COD iunction'with the accon'ipanying drawings, in which an embodiment of which the in-. vention is susceptible, is disclosed, it being obvious that changes and modifications ma y be resorted to without departing from the spirit of the appended claims forming a part he "eof.

In the drawings, 1 is a general or diagrammatic view of the apparatus, showing 1924. Serial No. 724,392.

it installedv in connection with an earthwell. with its parts in their operative positions, for forcing or pumping the water from the well.

Fig. 2 is an enlarged view partly in sec tion and partly in elevation taken on line 22 of Fig. 3 looking in the direction indicated by the arrows, showing certain parts of the apparatus mounted on a suitable support therefor and in the positions illustrated in. Fig. 1. i

Fig. 3 is a view of like parts in similar positions looking in the direction of the pressure controlling cylinder mounted on the said support but with the support interposed.

Fig. 4 is a similar view to Fig. 2 showing about the positions the parts will occupy when air pressure is shut off from the sou r ce of supply, and is being exhausted from the air tank located within the well.

Fig. 5 is a greatly enlarged sectional view of a diaphragm and its casing used in con-' nection with the apparatus.

Fig. 6 is an enlarged view in side elevation of parts of the connections leading from the master valve of the apparatus to the pres sure controlling cylinder and their valves for controlling the flow of compressed fluid between said valve and cylinder, and

7 is an enlarged plan sectional view taken on line 7'? of Fig. 6.

Like numerals of reference refer to corresponding-parts throughout the different views of the drawings.

Referring now more particularly to Fig. 1 of the drawings, the reference numeral 10 designates a water or liquid container such as a well, in which is suspended so preferably to be entirely submerged in the water 11 of said container, a tank 12 which is hermetically sealed except at its bottom or lower portion, in which is provided a portor opening 13 having around the sameon the upper surface of said bottom, or on the inner surface of the tank 12, a valve seat 14-. to co-act with a gravity valve 15 for the purpose ofadmitting water to said tank.

Located near the well or container, or at any suitable distance therefrom, is a large reservoir 18 for holding the compressed air, which may be supplied thereto by any suitable means and in suflicient quantity for use for a considerable length of time. Leading from this reservoir is a pipe 19 which is equipped with a pressure reducing valve 20 of the ordinary or any well known construction and communicates with a valve casing 21 which forms part of a larger or master valve casing which latter casing may be mounted on a suitable support 23 located near or remote from the well or liquid container l0 and supported in any suitable manner. The valve casing 21 has a port 16 leading to the casing 22', which port is surrounded by an upwardly extended valve seat 24 for co-operation with a valve 25 the stem 26 of which is mounted on a bar 27 hinged or loosely and adjustably connected at one of its ends for vertical movement for instance, to a screw 17 or other suitable projection depending from the upper surface of the valve casing 22 near one end thereo't.

The valve casing 22 is provided prelerably on its upper surface near its end opposite the member 17 with an exhaust valve casing 28 which is provided with one or more ports 29 and has vertically and slidably mounted therein a valve stem 30 which carries on its lower end a valve 3 to close the val vc seat ot the casing 28.

Depending "from the valve 31 is an extension 33 which is reduced towards its lower end and provided on said end with a head or enlargement The bar 27 which. (so-operates with the valve stem 26 is provided with an elongated slot 35 at its tree end for loose enga einent with the reduced portion ot the G TPDSiOI1 ot the exhaust valve. The upper end of the valve stem 30 is provided with head 36 having" thereon a horizontally extended arm 37 for the purpose to be presently explained. Fulcrumed on the lo r portion of the support 23 is a lever which is adapted to operate in a slot 39 in said support and to cooperate at one of its ends with the head 36 of the valve stem 30 for closing the valve 31. under certain conditions. I

Leading from the valve casing 22 is a pipe 41 which is extended througrh the cover oll or water container 10 communicates at its lower end with the upper end of the tank 12 to which end is said tank it a be secur d in such a manner to as. .t ii supporting the same. This last mentioned pipe employed conveying pressure from the master valve casing 22 to the tank 12 and may fixed to the cover oi the water container in any suitable manner so as to assist in supporting the said tan i. The upper portion oi the support 2 has journaled thereon a pulley 4% over which is extended a cab e which is connected at oi its ends to t 1e upper end of a longitudinally bored weight lfi which has the lower end of its bore contracted as at d3 in Fig. 2 ot the drawings.

Slidably located in the bore or cavity of the weight 46 is a rod 47 which has on its upper end a conershaped head 4-8 to restrict the movement of said rod in a downward direction. The rod 47 extends into a vertically disposed guide 48 mounted on a bracket with which the support 23 is prouded at a suitable distance above its lower end.

Rigidly mounted on the lower end of the rod 47 is a weio'llt 50 which is adapted for vertical movement in the guide 48. The other end oi the cable has secured thereout it, .uiiddle a cross-piece 54 from which d a pair of connections which are connected at their lower ends to a crosspiece in such a way that the connections will stride the controlling cylinder 57 l is e'rticz-cll mounted on the support tihle point thereon; the crosspieces d 56 are disposed in parallelism with one another in such'a way that their '2 1 of travel will diametrically intersect the cylinder 57 in the operation ol th ap- Extended from the upper end of the cylinder 5. is an elbow pipe 51 which has connected thereto a T-coupline' 52 provided with a removable p ug 53 in its sten'i, which can removed. to permitlubricant to be supplied to the interior oi the cylinder for lubricating the piston head tl'lereot. Connec ed to the outer end of the coupling one end of another T-couplin" designated as a whole by the numeral o2 the stem 55 of which constitutes the casing; tor a needle valve 54 seatwl in the r'nember 53 so to open and close a port in said member leading: into a channeled valve casino 55 which is horizontally extended lronr the en'iber 53 above the coupling is clearly shown in .Fig. and (3 of the drawings. This valve casing 55 is provided with an outlet port 5 near its tree end and abou midway between its ends on one side thereot with a ecrew-threaded stem 57" disposed at a r ght angle to the casing 55 as shown in Fig. 7 of the drawings.

Pivot-ally mounted on the stem 57 is a valve bar 58 which is pressed against the adjacent side of the casing by means oi a spring; 59 coiled around the stem 57" and restin c at one of its ends against the member of? and at its other end a nut atino' the stem 57 used for r., F lfld spring. Pivotally connectet r Boer end to that end oi the valve jacent the cylinder is a rod (1 tlre lower end oi which is adjustablv sethe arm carried bv the stein 2-3-0 exhaust valve of the mad er valve cas- 2 as will be readily understood bv re'l e to r 2 and a; oi the drawin e s. utel in the outer end of the T-coupling f is another T-shaped coupling or valve casing 62 which has connected to the stern thereof the upper end of a pipe 63 the lower end of which is connected preferably by means of a coupling64c with the master valve casing 22 usually on top thereof. Adjustably fitted in the end of the valve casing or T-coupling 552 remote from the cylinder 57 is a needle valve 65 employed for regulating the flow of compressed air from the easin 22 into the controlling cylinder.

' y the arrangement of the parts 51 to 6d inclusive, and in addition by the employment of the pipes 19 and 41 communi ating with the master valve casing 22, it is ap' parent that a connection communicatably uniting the tank 12, the reservoir 18 and the pressure controlling cylinder 57 is provided by means of which not only the flow of compressed air from the master valve casing 22 into the controlling cylinder can be regulated, but also that the exhaust from said cylinder can be positively controlled in such a way as to prevent accumulation of condensationin the pipe 63 leading;- from the master valve tothe valve casing: 62 as frequently occurred and was found objectionable in the pipe for a corresponding pur-.

pose of my aforesaid application. Furthermore,-by my present improvements a valve controlled exhaust or vent casing; for the pressure controlling cylinder 57 of such a characteras to prevent at all times leakage on account of the wear of certain parts of an arrangementor construction for the same purpose employed in my a oresaid pending application, .is provided lit; the use of the spring-pressed sliding valve bar 58 and its parts co-operating with the exhaust valve of the master valve casing; of the apparatus.

Extended through the cover as of the well or water container is a service pipe 65 which may be equipped with a branch pipe 66 and afaucet 67 for drawing water from the tank 12, into which the pipe 65 is extended to a point near thebottom of said tank. This pipe-65 is also connected to the cover 42 and the top of the tanlr12 so as to assist in supporting-said tank.

By reference to Figs. 1, 2 and 4 of the drawings it will be seen and understood that the lever 38 is so located and supported on the support that one of its ends will be located in the path of the travel of the weighted while its other end islocated in the path of travel of the head 36 on the stem of the exhaust valve of the master easing". It will also be observed that the lever 38lias the upper portion of its ends rounded to form bearing surfaces for toaction with the lower surfaces of said head and weight. By thus locating the lever 38., it is evident that upon the downward movement of the weight 50 the same will strike the rounded portion of one end of said lever and cause the same to be depressed as shown in Fig. 2 of the drawings, when the compressed fluid shall have been exhausted from the controlling cylinder. In this movement .Figs. 4 and 5 of the drawings.

of the parts it is manifest that the exhaust valve in communication with the valvecasing 22 will be closed and that at the same time the inlet or supplyvalve for compressed air will be opened and remain in such position as longflas the weight remains in contact with the lever 38 an d that when the parts are thus positionedas just above mentionech the sliding valve bar 58 will. be closed. 3

Mounted on a suitable bracket 66 extended from the upper portion of the guide 48 is a diaphragmeasinp; which comprises a pair of convex disks or members 67 and 68 which I have their concave surfaces facing each other and are secured together in any suit able manner. *Located between the memhers 67 and 68 is a diaphragm 69 of rubber or any other suitable material which is held by the members of the diaphragm casing near its edges. Extended through a suitable opening in the member 68- is a slidal'ile rod 70 which by preference has on its end adjacent the diaphrafrm an enlargeineiuz 71 to rest against said diaphragm. The opposite end of the rod 70 rests against an arm or plate 72 which is pivoted to the bracket 66 and extends downwardly therefrom and has at its-lower portion a laterally extended arm 73 provided with a projection 74 extended downwardly orlaterally from said last named arm.

. The member 72 isprovided in its portion. below the arm 7 3 with a transverse opening in which is slidably located a trip rod 7 5 which also extends through an opening in the extension 74 and has its end adjacent said extension screw-threaded for engage-- ment with a nut or nuts 76 used for reg ulat ing'the'tension of a spring 77 surrounding the trip rod 7 5 between the extension 74 and the member 72 below the arm 7 3 thereon. One end of the spring'77 rests against the extension 74 while the other end of said spring rests against an enlargement 7 6 car ried by the rod 75, by which arrangement it is manifest that the rod can be ad vanced or retracted as desired and the tension of the spring 77 actuating said rod regulated. Fixed at one of its ends to the lower portion of the member 72 is a rod 79 which is movably extended through a suitable opening in the lower portion of the diaphragm casing as is clearly shown in Surround.- ing the rod 7 9 and resting at one of its ends against the diaphragm casing on that surface thereof opposite the member 72 is a spring 80 the other end of which spring rests against the washer 81' which is mounted on the rod 79 near its outer end, which washer is held in constant contact with the spring 80 by means of an adjusting nut 82 threaded on the outer end of the rod 79 and employed for the'purpose of regulating the Lil tension of the .ned u 1 operating the tri:

functions oi plained.

When the parts are in the. positions shown in it is obvious that the sliding bar valve 58 will he moved so to open the port 56 of the valve casing 55 thus permitting the exhaust of air from the cylinder 57 through the elbow pipe 51, couplings 52 and 53, as well as the casing 55, and that thus pressure in the cylinder 57 will be re duced to such an extent as to permit ti e weight 46 to descend independently oi? tie rod 4:7 and weight 50, at whichtime the cross-piece 56 carried by the piston rod will strike the lever 86 thus causing the hook 90 to be disengaged from the weight 50. This last named weight will now-be held by the trip pin or rod actuated by the diaphragm when the faucet 6'? is open for the withdrawal of water, which will reduce the pressure in the expansion chamber 8a and through the pipe 83 in the diaphragm casing to such an extent as to permit the tension exerted by the spring to disengage the trip pin 75 from the weight 50, when the same will automatically assume the position shown in Fig. 2 of the drawings.

By positioning the needle valve 65 in the connection or means for controlling the pressure in the cylinder 57 at near the upper end of said cylinder and by employing the vertically disposed pipe leading from the said needle valvecasing to the master valve casing, it is obvious that accumulation of condensation in said pipe will be avoided and furthermore, that said needle/valve will be located in a more accessible position. It is further apparentthat by employing the sliding valve bar 58 constructed as set forth for the valve casing 58 wear of the parts will be compensated toil-by the pres sure of the spring 59 against said valve bar thus preventing liability of leakage of air to such an extent as to afi'ect the eiiiciency oi the apparatus.
